  • Patent number: 10380987
    Abstract: Methods and apparatuses for addressing open space noise are disclosed. In one example, a method for masking open space noise includes outputting from a speaker a speaker sound corresponding to a flow of water, and displaying a water element system, the water element system generating a sound of flowing water.
    Type: Grant

  • Patent number: 9978357
    Abstract: Methods and apparatuses for headphones are disclosed. In one example, a noise cancelling signal is generated with an active noise cancelling system, and the noise cancelling signal is output at a headphones speaker. An undesirable user effect resulting from the noise cancelling signal output at the headphones speaker is mitigated with a noise cancelling adverse effect counteraction signal output simultaneously with the noise cancelling signal.

  • Patent number: 9980028
    Abstract: Methods and apparatuses for user sound exposure limiting are disclosed. In one example, an accumulated sound dose exposure from a headset speaker is determined for a plurality of sequentially monitored time intervals during a current listening session, wherein the current listening session comprises a total session time. It is determined whether a predicted sound dose exposure for the total session time exceeds or falls below a permitted sound dose exposure limit, the predicted sound dose exposure determined from the accumulated sound dose exposure. A threshold intervention level at which a time-weighted-average limiter at a headset applies attenuation to an audio signal output at a headset speaker is adjusted.

  • Patent number: 9620141
    Abstract: Methods and apparatuses for addressing open space noise are disclosed. In one example, a method for masking open space noise includes outputting a test signal from a speaker, the test signal operable to measure a speech transmission quality of a transmission channel. The method includes receiving the test signal at a microphone, outputting a detected test signal, and processing the detected test signal to determine the speech transmission quality of the transmission channel. The method further includes adjusting an output level of a noise masking signal from the speaker responsive to the speech transmission quality.

  • Patent number: 7190797
    Abstract: A telephone headset utilizing a foldable microphone boom that is operable in both noise canceling and omnidirectional modes is disclosed. The headset generally comprises a main body, a boom extending between a pivoting end and a microphone housing for housing a two-port microphone, and a pivoting hinge coupling the pivoting end of the boom to the main body and enabling the boom to rotate about the pivoting hinge relative to the main body. The boom is adapted to be positioned in a first extended position in which the microphone is located away from the main body and both ports are open and a second folded position in which the microphone housing is at least partially in contact with the main body to generally close one of the ports.
